Today, while painting a wall, I handed a bucket of paint up to my friend who was standing on the top rung of a ladder. She said she felt dizzy, and came crashing down on me, along with the paint on my head. FML

You can get dizzy anywhere, anytime, anyplace! Whether it be at the top of a ladder or sitting on the recliner. (Weird example, I know! It was the first thing I could think of!)
Slow circulation or lack of oxygen to the brain causes dizziness. And anything can cause those two things to happen.

Today, while painting a wall with my friend, I got dizzy & fell from the top of the ladder , the can of paint fell with me & the jerk was more concerned of the paint falling on him than me falling from the top of the ladder. FML
